Abstract
The utility model provides a kind of sealed valve for regenerative chamber incinerator, including valve shell and the rotation flap being arranged inside valve shell, the valve shell is integrally in T shape, there are two import and one outlets for tool, the side of the rotation flap far from outlet is fixedly connected with shaft, the rotation outer wall of the flap far from shaft side is fixedly connected with valve shell, and rotation flap corresponding position is provided with opening, it is open there are one being set in the position that the rotation flap both sides correspond to import and one silent, and then limit medium chute inside the rotation flap, wherein, it is equipped with the groove of clamping sealing ring in the silent position of the rotation flap, it is welded with hard alloy layer in the outside heap of the sealing ring, the width of the hard alloy layer is 25 ~ 30mm, thickness is 2 ~ 5mm.The good seal performance of the utility model, new structure make valve be unlikely to deform, and the performance that sealing is irised out is more preferable.
Description
Technical field
The utility model is related to a kind of sealed valves for regenerative chamber incinerator.
Background technology
Regenerative chamber incinerator valve aperture is big, and valve switch frequently, substantially switchs once in 1min, and valve is in cold and hot shape
State alternately changes.It is particularly easy to that the corrosion of valve sealing face and valve seal facial disfigurement is caused to lead to valves leakage in this way, causes
System VOCS（volatile organic compounds）Volatile organic matter removal rate declines, and flue gas emission is not up to standard.
Therefore, the technical problems such as it is badly in need of a kind of new sealed valve to overcome valve sealing face yielding.
Invention content
One purpose of the utility model is to provide for a kind of sealed valve for regenerative chamber incinerator, sealing performance
Good, new structure so that valve is unlikely to deform, and the performance that sealing is irised out is more preferable.
Particularly, the utility model provides a kind of sealed valve for regenerative chamber incinerator, including valve shell and
The rotation flap being arranged inside valve shell, the valve shell is integrally in T shape, there are two tools import and one outlet,
The side of the rotation flap far from outlet is fixedly connected with shaft, the rotation outer wall and valve body of the flap far from shaft side
Shell is fixedly connected, and is rotated flap corresponding position and be provided with opening, is set in the position that the rotation flap both sides correspond to import
There are one opening and one are silent, and then medium chute is limited inside the rotation flap, wherein in the rotation flap
Silent position be equipped with clamping sealing ring groove, be welded with hard alloy layer, the hard in the outside heap of the sealing ring
The width of alloy-layer is 25 ~ 30mm, and thickness is 2 ~ 5mm.
Preferably, the hard alloy layer is nickel-base alloy or nickel cobalt (alloy).
Further, the region that the closed end of the rotation flap is in contact with valve shell is arc.
Compared with prior art, the utility model has the advantage of：
The utility model limits medium flow field by the way that sealed valve is designed to revolving valve flap structure in flap
Road so that whole better tightness, while irising out butt welding hard alloy in sealing so that the corrosion resistance and intensity of sealing surface
Higher.
According to the accompanying drawings to the detailed description of the utility model specific embodiment, those skilled in the art will be more
Add the above-mentioned and other purposes, advantages and features of clear the utility model.
Description of the drawings
Some specific realities of the utility model are described in detail by way of example rather than limitation with reference to the accompanying drawings hereinafter
Apply example.Identical reference numeral denotes same or similar component or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.In attached drawing：
Fig. 1 is the structural representation according to the sealed valve for regenerative chamber incinerator of the utility model one embodiment
Figure.
Specific implementation mode
Present embodiment describes a kind of sealed valves for regenerative chamber incinerator, as shown in Figure 1, including valve shell 1
With the rotation flap 2 being arranged inside valve shell 1, the valve shell 1 is whole in T shape, and there are two import and one for tool
Outlet, the side of the rotation flap 2 far from outlet are fixedly connected with shaft 5, and the rotation flap 2 is far from 5 side of shaft
Outer wall is fixedly connected with valve shell 1, and is rotated 2 corresponding position of flap and be provided with opening, is corresponded in 2 both sides of rotation flap
The position of import is set there are one opening and one are silent, and then limits medium chute inside the rotation flap 2, wherein
It is equipped with the groove of clamping sealing ring 3 in the silent position of the rotation flap 2, is welded with firmly in the outside heap of the sealing ring 3
The width of matter alloy-layer 4, the hard alloy layer 4 is 25 ~ 30mm, and thickness is 2 ~ 5mm.
Preferably, the hard alloy layer 4 is nickel-base alloy or nickel cobalt (alloy).
Further, the region that the closed end of the rotation flap 2 is in contact with valve shell 1 is arc.
The present embodiment limits medium flow field by the way that sealed valve is designed to revolving valve flap structure in flap
Road so that whole better tightness, while irising out butt welding hard alloy in sealing so that the corrosion resistance and intensity of sealing surface
Higher.
So far, although those skilled in the art will appreciate that the more of the utility model have been shown and described in detail herein
A exemplary embodiment still, still can be according to the utility model public affairs in the case where not departing from the spirit and scope of the utility model
The content opened directly determines or derives many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new
The range of type is understood that and regards as to cover other all these variations or modifications.
